To all whom it may concern:

Be it known that 1, JOHN G, Ynisna, Jr, citizen of the United States,residing at Omaha. in the county of Douglas and State of Nebraska, haveinvented certain new and useful Improven'ients in Feed-Controlling Meansfor lnternal-Combustion Engines, of which the following is aspecification.

This invention relates to feed controlling means for internal combustionengines, adapted for use in connection with all engines of this class,movable or stationary, and found to be particularly useful for theengines of automobiles, and has for its object, broadly, to provide suchan arrangement of parts that superheated steam may be introduced to thefuel intake in greater or lesser quantities, as may be required forvarying speeds, weight of the load, or moving upon inclines, the use ofthe superheated steam resulting in economizing fuel, and thesubstituting of superheated steam for cold air for mixing withhydrocarbon, this being particularly of advantage during cold. weather,also for preventing adhesions of carbon within the cylinders and. valveswhich communicate with the cylinders, and resulting, generally, inincreasing the editciency of the engine.

The invention includes a construction of parts, whereby hot water, byoperationpf suction, will be removed from the water jacket or othersource of supply, and will be moved through an indicator on the dashboard or other support convenient to the driver or operator, to anelevation which will beabove the water jacket or other water supply, andfrom the indicator will be moved through a coil in the exhaust manifoldwhere it will be exposed to a high degree of heat, and from thence willbe conducted and will be discharged within the intake manifold, suitablemeans being provided for a control of this supply.

The invention also includes means found to be of advantage forintroducing superheated steam to the intake manifold which is operatedin. conjunction with the valve of the carbureter, and which providesadjustmerits so that theproportion of superheated steam supplied may begreater or less, as ma j be required. The invention alsohas reference tosuch a construction of parts that operation, for the most part, will beautomatic, and may be readily applied to the engine at the factory whenfirst assembled or at any time thereafter.

With the foregoing objects in view and others to be mentioned, theinvention presents a novel construction, combination and arrangement ofparts as described herein and claimed, and as illustrated in theaccompanying drawing. wherein,

Figure l is a view in side elevation of an engine and parts of anautomobile, showing the device applied thereto, parts being broken away,and the dash board of the automobile being in section. Figs. 2, 3, 4, 5and 6 show enlarged details. Fig. 2 is a front view of an indicatingdevice. Fig. 3 is a sectional view on line 3 3 of Fig. 2. Fig. 4 is asectional view on line 1 4 of Fig. 2. Fig. 5 is a view in longitudinalsection of a strainer-plug. Fig. 6 is a view. in longitudinal section ofan apertured distributingplug.

Referring now to the drawing, numerals 7 and 8 respectively indicate thecylinders and water jacket of an internal combustion. engine, thecarbureter, intake manifold and exhaust manifold of the engine,respectively being indicated at 9, 10 and 11.

At 12 is indicated a sight-indicating device which is mounted upon thedash board 13 at any suitable altitude abovethe water jacket or othersource of water supply. While I do not wish to limit myself to anyparticular form or arrangement of an indicating device, it preferablyconsists of a suitable casing 14 provided with a transparent part 15 andwith a horizontal compartment 16 having an intake .17 and upon which maybe mounted a water conducting pipe 18 which communicates with the waterjacket 8 and said intake 17 a plug 19 being provided for and inserted ina suitable aper ture (not shown) in the water jacket, said plug 19 beingprovided with a suitable strainer 20 (Fig. 5.) to prevent sediment frompassing to the conducting pipe 18.

The casing is also provided with a pas sageway 21 (Fig. 3.)communicating with the compartment 16 and with its main chamber 22, saidpassageway being under control of a needle valve 23 which may beconveniently adjusted to permit water to drip from a depending nipple24: through the main chamber andto pass to a second conducting pipe 26provided with a coil 01 disposed in the exhaust manifold 11, and

having a part 7) extending from the exhaust manifold to communicate withthe intake incoming superheated steam so that it will with the mainchamber 22 of the casing by become immediately mixed with hydrocarbon.

. The casing 14 is also provided with a second passageway 29 (Fig. 4.)which communicates with the compartment 16 and passing through adepending nipple 24, said passageway 29 being controlled by a needlevalve 30 which is provided with an arm 31 having apertures 32 formedtherein at longitudinal intervals.

The conventional gas-throttle-rod for controlling the movement of.hydrocarbon from the carbureter to the intake manifold is indicated at33. Numeral 34 indicates the conventional valve for the carbureter, thepivotally connected links which form a connection between the lower endof the rod 33 and the lever c of said valve, being indicated at 35 and36.

In order that the superheated steam, produced by the arrangement ofparts as described, ma be supplied to the intake manifold coinci entlywith the supply thereto of hydrocarbon through the valve 34 of thecarbureter, I provide for the rod 33 a crank-arm 37 and also provide alink or rod 38 having its respective ends pivotally connected with thecrank 37 and engaging in one of the apertures "32 of the arm 31 of theneedle valve 30. 7

As described, it is obvious that an operator, when imparting the usuallimited movement to the rod 33 by use of its handle (Z for its rotationto open the valve 34 for permitting hydrocarbon to enter the intakemanifold, will also move the crank arm 37 for opening the valve 30, anda reverse movement of the rod 33 will cause the valve 30 to move to itsseat. Also if the link 38 engages in one of the apertures 32 of arm 31comparatively near the valve 30, the degreeof rotation of said valvewill, obviously, be greater than would be caused by an engagement of thelink in an aperture more remote.

In operation, a limited quantity of hot water or steam will be elevatedto compartment 16 by suction, and on account of suction will move to andthrough the coil a subject to the means for control mentioned. The wateror steam which enters the coil will, of course, be subjected to a highderee of heat, and will enter the intake maniold as superheated steam.On account of the construction as described, the superheated steam willbe immediately divided and will be mixed with the hydrocarbon so thatignition will occur to advantage thereafter.

The valve 23 may be adjusted to permit a limited, uniform quantity ofwater to pass from the compartment 16 to the pipe 26, and this valve isnever closed. Water will not pass this valve except by action ofsuction, and flooding of the intake manifold with water while the valve23 remains open is quite impossible since it is disposed at an elevationabove the water supply or water jacket As soon as the engine commencesto operate, there will, of course, be an operation of suction, and hotwater will begin to pass the valve 23.

When a heavy load is being drawn or when moving up an incline, and agreater quantity of hydrocarbon is required. it is obvious that theconstruction provided is of great advantage, since, by the arrangementdescribed, the quantity of superheated steam supplied to the intakemanifold will be in proportion to the quantity of hydrocarbon suppliedthereto.

It will be appreciated that some advantages are to be derived byconnecting the conducting pipe 18 with the water jacket, but I do notwish to limit myself in this respect, and the water may be supplied fromany other desired container having a water level lower than the heightto which water may be conducted by the pipe 18, to prevent an overflowthrough the normally open valves 23 and 30. Also the device would beoperative without the visible features provided by the casing 14 andmembers 15. 24: and 24:, and one of the valves 23 or 30 could bedispensed with, and, in each instance, the device would be fairlyoperative, and the specific construction for members 19 and 28, and manyminor details could be changed, within the scope of the claims. What hasbeen shown and described relates to the preferred construction andconstitutes one embodiment, only, of the invention.
